Humanity already possesses the fundamental scientific, technical, and industrial know-how to solve the carbon and climate problem for the next half-century. A portfolio of technologies now exists to meet the world's energy needs over the next 50 years and limit atmospheric CO2 to a trajectory that avoids a doubling of the preindustrial concentration. Every element in this portfolio has passed beyond the laboratory bench and demonstration project; many are already implemented somewhere at full industrial scale. Although no element is a credible candidate for doing the entire job (or even half the job) by itself, the portfolio as a whole is large enough that not every element has to be used.

Magnetorheological elastomers (MREs) are a class of recently emerged smart materials whose moduli are largely influenced when exposed to an external magnetic field. The MREs are particulate composites, where micro-sized magnetic particles are dispersed inside a non-magnetic polymeric matrix. These elastomers are known for changing their mechanical and rheological properties in the presence of a magnetic field. This change in properties is widely known as the magnetorheological (MR) effect. The MR effect depends on a number of factors such as type of matrix materials, type, concentration and distribution of magnetic particles, use of additives, working modes, and magnetic field strength. The investigation of MREs’ mechanical properties in both off-field and on-field (i.e. absence and presence of a magnetic field) is crucial to deploy them in real engineering applications. The common magneto-mechanical characterization experiments of MREs include static and dynamic compression, tensile, and shear tests in both off-field and on-field. This review article aims to provide a comprehensive overview of the magneto-mechanical characterizations of MREs along with brief coverage of the MRE materials and their fabrication methods.

textCurrently, companies spend a great deal of effort on Corporate Social Responsibility (CSR) disclosures. CSR disclosure relates to the provision of information on companies' environmental and social performance. From an economic perspective, companies might disclose this information to avoid or decrease potential political costs. We construct a CSR disclosure index based on the Global Reporting Initiative (GRI) guidelines. Using content analysis, we analyze 130 listed German companies' CSR disclosures (470 firm-year observations) to investigate the determinants of these voluntary disclosure activities. Our results show that, consistent with the political cost theory, German companies' disclosures of all CSR issues are affected by their visibility, shareholder structure, and relationship with their US stakeholders. In addition, higher profitability is associated with more environmental disclosures. Finally, size and industry membership affect the amount of CSR disclosure.

Learning is a process of adding insight, improving skills, and changing attitudes for the better. In introducing the shape of the room, the teacher finds it difficult to embed the concept, by using the online media geoboard to make it easier to understand the concept of flat shape. This study aims to describe how the influence of using Geoboard online in improving students' understanding of mathematical concepts in the learning of Bangun Datar in the fourth grade of elementary school. Type of research This type of research uses the Mix method, namely data collection using qualitative and quantitative. Sampling using purposive sampling with a total of 28 students and research design using Explanatory Sequential Design. This study involves several variables as research categories, namely student responses and concept understanding. Data analysis used descriptive and inferential statistics. The result is that the response variable and concept understanding have a significant effect, with a value of sig <0.05 and on each dominant variable in the good category, so that the online geoboard media has an effect on students' understanding of the flat wake concept. Therefore, the use of geoboard online media can be used as an alternative to fun learning and is appropriate for the age of elementary school children. In addition to making it easier for teachers to introduce hereditary culture, namely games, students are also more active in learning.

Worship is the main task that Allah SWT has entrusted to humans while standing on earth. There are many ways of worship, which if summarized into two types, namely mahdhah worship (pure / without intermediaries) and ghairu mahdhah worship (impure / through intermediaries) where worship performed by Muslims has several conditions so that their worship is accepted, one of which is purification. Based on the analysis of the problems received by the author from the community in Pantai Harapanjaya Village, there are still many children and adolescents who do not fully understand and practice the correct procedures for purification according to the guidance of Islamic law. Because of the problems that exist, the author uses the lecture and demonstration method on the material for correct purification training procedures according to the guidance of Islamic law which are held in two meetings, where the first meeting uses the lecture method which is held at the Al-Husna Mosque in Bulak Hamlet and the second meeting uses the lecture method. demonstration method carried out in the Saung Ilmu Bulak Hamlet. The results of the conclusions from these two activities include, firstly increasing understanding and increasing children and youth in carrying out the practice of purification properly according to Islamic sharia guidelines and secondly increasing trust in the community and parents towards children and adolescents that they have been able to become the golden generation to continue the struggle for progress in Harapanjaya Beach Village with the initial capital of having a pure soul from an early age.

This study aims to evaluate the characteristics of accession of Bengal grass that grows in the city of Jambi. The research was conducted in two stages, namely the field observation stage to obtain qualitative data and quantitative data related to the characteristics of Bengal grass. The results of the observation phase were validated to obtain four accessions that had the same morphological characteristics. There were four accessions which were then planted in polybags in a greenhouse, namely Tlp1, Dns2, Jlt1 and Ktb2 as treatments with repeated 10 times. The design used was a completely randomized design. The parameters observed were plant height, leaf length, leaf width, internode length, number of internodes, stem circumference and leaf color. The results showed that the Jlt1 accession was an accession that had different characteristics (P <0.05) compared to other accessions.

PT ABC merupakan perusahaan yang bergerak di bidang teknologi informasi, menyediakan berbagai produk untuk mendukung infrastruktur di bidang teknologi, security system, Private Automatic Branch eXchange (PABX), telekomunikasi dan jaringan. Perusahaan memiliki permasalahan yaitu tidak adanya dukungan review dan komentar, kurangnya informasi mengenai produk dan layanan, serta penyimpanan data pelanggan yang tidak maksimal. Dalam upaya meningkatkan pelayanan dan kepuasan pelanggan memerlukan strategi bisnis yaitu dengan menerapkan konsep Manajemen Hubungan Pelanggan. Untuk mengatasi permasalahan tersebut maka dikembangkan sistem informasi manajemen pelanggan berbasis website. Metodologi yang digunakan untuk membangun sistem informasi manajemen pelanggan adalah metode RUP (Rational Unified Process). Implementasi sistem akan menggunakan bahasa pemrograman PHP (codeigniter), javascript dan MySQL sebagai databasenya. Pembuatan sistem yaitu memberikan informasi yang up to date kepada pelanggan, selain itu memudahkan pelanggan untuk memberikan masukan dan saran sehingga PT ABC dapat memberikan pelayanan prima dan dapat meningkatkan loyalitas pelanggan.
